To all whom it may concern Be it knownthat we, LAWSON CLARK and GEORGE Gr. JEFFERY, citizens of the United States of America, and residents ofBarnesville, county of Belmont, and State of Ohio, I

. stretching one or a plurality of fence wires.

The primary object of the invention isfto provide a simple, durable and conveniently operated stretcher. for the wires of wire fences.

Afurther object is to provide a stretcher frame designed for mounting in a stationary position and adapted tobe operated by one man. i v

A still further object is to provide a wirestretcher of the jack-screw type having means whereby the jack-screw thereof may be quickly removed from and replaced inits mounting in retracted, or initial stretching, position without the tedious operation of reversely screwing it to. said position.

With these and other objects in view, the

invention resides in the features of construc- 7 tion', arrangement of parts and combina tions of elements which will hereinafter be fully described, reference being had to the accompanying drawings,-forming. a part of.

. tion, showing the same as it appears in initial stretching position; Fig. 2 is a similar view, showing the wires stretched to the limit of the draw of the jack screw a'ndpthe means for holding said wires taut while the jack-screw is being returned to initial position; Fig. 3 is a section on the line 3-3,

Fig. 1; Fig. 4 is a section 0n the line 4-4,

i Fig. 1; Fig. 5 is a top plan view, enlarged,

of the jack-screw mounting; and Fig. 16 is a face view of the same.

- Referring to saiddrawings, in whichlike designating characters distinguish like parts throughout the several viewsl indicates a frame composed of any suitable material and embodyinga pair of parallel upright"- bars 2 disposed at a distance apart to form an intervening opening 3 of suitable dimensions. Rigidly mounted vupon one face of said frame is a pair of horizontally disposed arms 4 which are. designed to have their j When'the ack-screwthelimit'of itsforward movement, as shown,

Formounting the frame 1 with its arms against a post, suitable clamps are prov ded,sa1d clamps consisting of horizontal rods 6 each of which has a threaded end slidably mounted ina laterally directed i arm or lug 7provided onsa-id frame and has its opposite end shaped to form a hook 8 adapted for engaging the post on the side opposite that engaged by the arms j 4. Cranks 9 threaded upon thethreaded ends of said rods 6 a-gainst the outer faces of said lugs 7 are employed for adjusting said rods:

with the wires 12 to be-stretched The in-' ner end of said jack-screw carries a swiveled ring l3 to whichisattachedone or more chains 14, whic h are adapted for connection to hooks or-rings 15 carried by a suitable clamp 16which rigidly' 'gripsthe wire or wires 12 to be stretched, A crank 17 fixed disposed ina mounting. or,

upon the outer end of" said jack-screw af- 3 fords means whereby power maybe applied 1 for rotating the latter toefl'ectthe'stretching of the wire'or wiresb in dotted lines in Fig. 1 and in full lines in c i 'Fig. 2, a cable or chain 18 is attached to, or

isflooped around the clamp 16"and, being chain serving to prevent retraction of the fence wires when the jack-screw is relieved drawn up tight, has its ends detachably conof tension. as when the latter is returned to its initial position for continuing the stretchingoperation.

In order that the jack-screw may occupy a position wherein the draft chain or chains 14 will not engage the post 5, the arms 4 preferably have a slight lateral inclination,

as is most clearly illustrated in Fig. 4.

The head-pieceorinounting, which is designated generally by the numeral "10. is of a special novel form designed to admit of quick adjustment of said jack-screw from one position to another when not under ten-v sections 20 and 9.1,the former having oppositely disposed trunnions 22 at its opposite sion. It comprises two complemental body l ends. Said head-piece'is adapted to occupy I has been rotated to a a position in the opening 3 between the upright members2of the frame, with its trum nions 22 removably mounted in suitable seats, as recesses or notches 23, provided said upright members. A plurality of such seats 23 is preferably provided, the same,

being arranged in pairs, thus affording means which permit of the vertical adjustment of said head-piece to a most convenient or desirable position. v

The section 20 is of substantially Vgshape in face elevation, and has one-half of the threaded bore 24 for the reception of the jack-screw located at the angle of the V. The section 21 is complemental to said section 20, being adapted to fit closely on the V-shaped face of the latter, to form a body of'rectangular shape, and has the other half of said bore complementally located. Said sections are pivotally connected, or hinged, adjacent oneendof thebody, the section 20 havingan upright lug 25receive'd in a corresponding recess 26 in the section 21, and a pivot pin 27 being directed through said lug and'the portions of said section 21 located at opposite sides of said recess 26; A vertical pin 28 having a Winged head 29 has its lower body portion rotatably mounted in the section 20 adjacent to one end and has its upper body portion received in a recess 30 provided inthe corresponding end ofthe section 21. When-said pin 28 occupies a position whereinthe wings of its head e X- tend in a direction longitudinal with respect to the body of the head-piece, the sec; tion 21 maybe freely raised and, lowered a Without hindrance, permitting the ready removal or insertion of the jack-screw. But, as is obvious, when said pin-1s turnedso that its wings overhe' thep'ortlons of said-seek tion 21 located at opposite sides of the recess 30, said sections are. firmly interlocked uponthe interposed jack-screw.

From the foregoing it will be seen that the invention is extremely simple in its construction, that it may be easily operated by one man without the necessity for an at tendant, and that it may be made strong and durable, ,there being few, if any, parts which are likely to become'out of order. It will furthermore be seen that the device is adapted for use for stretching wires on either side of the fence posts, a mere reversal of the position of the frame 1 being the only requirement to shift the stretching to the opposite side of the post from that illustrated in Figs. 1 to 4, inclusive, of the drawings.

lVhat is claimed is A wire stretcher comprising a pair of upright parallel frame members, means for mounting said frame members upon a fence post, a headpiece disposed between said frame members, a jack-screw mounted in said head-piece, and means for, attaching fence wires to said jack-screw, said head piece comprising a pair of complemental sections having hinged connection one with the other, one of said sections having trunnions seated on said frame members, and means carried by said sections whereby they are-rigidly interlocked upon the jack-screw.

Intestimony whereof we aflix our signatures in presence of two witnesses.
